ABSTRACT:
A method and apparatus for determining an optimal writing power for recording data on a recording medium such as an optical disk, are discussed. The method according to an aspect of the present invention includes (a) performing a plurality of OPC operations on a plurality of areas of the recording medium, the plurality of OPC operations being performed in mutually different manners, the plurality of areas being areas within a power calibration area (PCA) allocated in the recording medium; and (b) determining an optimal writing power for recording data on the recording medium based on writing powers detected via the plurality of OPC operations.
